T 0 all whom it may concern:

Be it known that I, KARL FREDRIK VVIL- HELM PETTERSSON, a subject of theKing of Sweden, residing at Edsbyn, in the Kingdom of Sweden, haveinvented a new and useful Improvementin Hairpins, of which the followingis a specification.

Many attempts have been made to produce a hair-pin which will besecurely fixed in the hair without being difficult to put in and drawout, but hitherto all such attempts do not appear to have led to thedesired result as there are still only to be found in the market theordinary hair-pins with straight legs or shanks or with wavy legs, whichtwo kinds of hair-pins easily drop out of the hair, as is well known,and will therefore not hold the hair securely.

The present invention relates to a hairpin which will be securely heldin and retain also thin hair and which is at the same time easy to putin and draw out and which does not cause any increased wear on the hair.The present hair-pin is broadly characterized by that at least one shankor leg of the same is bent back, preferably approximately opposite thepoint of the other shank, inwards between the shanks where it forms aresilient abutment approximately parallel to and cooperating with theother shank. When the hair-pin is put into the hair, the hair can easilyenter between the resilient abutment and the cooperating second shankand become gripped between the same, so that the hair-pin is securelyheld and in its turn holds the hair.

The accompanying drawing shows an embodiment of a hair-pin according tothe invention in side view in Fig. 1 and in edge view in Fig. 2.

As illustrated in the drawing, the one leg or shank 1 of the hair-pin isbent back inwards between the shanks so that at the bend it obtains apoint 2 approximately opposite the point 3 of the other shank 4. Theportion 5 of the shank 1 between the shanks 1 and 4 lies approximatelyparallel with and close to the shank 4 and forms an elastic or resilientabutment for said shank. As shown in Fig. 1, the point of the shank 4 isbent out from the portion 5 in order to produce an entrance opening forthe hair 1923. Serial No. 645,068.

between the points 2 and 3. When the hair I is introduced into saidopening the portion 5 springs back from the leg 4 approximately to theposition 5 indicated by a dotted and dashed line, depending upon thequantity of hair, and the hair will then of course become grippedbetween the shank 4 and the portion 5. Said portion 5 lies in the planeof the shanks 1 and 4, as will be evident from Fig. 2, and in order thatduring its movement the portion 5 shall move in said plane it isprovided with a guide which, in the embodiment illustrated, consists ofan eye 6 which surrounds the arch 7 of the hairpin. In order moresecurely to grip the hair the shank 4 and the portion 5 may be bent intowave shape, as shown in Fig. 1, and it will be understood that suchwaves may also be made in the shank 1.

It will be understood that the invention is not. limited to theembodiment illustrated. The second shank 4 may for instance also beprovided with a portion bent inwards and corresponding to the portion 5which two portions will then cooperate and spring towards and away itromone another. The guide for the bentportion or portions may also be madein other suitable manner.

I claim:

1. A hair-pin having at least one of its two legs bent back inwardsbetween the legs and forming a resilient abutment approximately parallelto and cooperating with the other leg.

2. A hair-pin having at least one of its two legs bent back,approximately opposite the point of the other leg, inwards between thelegs and forming a resilient abutment approximately parallel to andcooperating with the other leg.

3. A hair-pin having at least one of its two legs bent back inwardsbetween the legs and forming a resilient abutment approximately parallelto' and cooperating with the other leg, said resilient abutment lying inthe plane of the two legs and being guided in such manner as to becapallole of moving only in the plane of said two egs.

4. A hair-pin having at least one of its two legs bent back inwardsbetween the legs and forming a resilient abutment approximately parallelto and cooperating with the other leg, said resilient abutment lying inthe plane of the two legs and being guided at the arch joining the twolegs of r the hair-pin in such manner as to be capable of moving only inthe plane of said two legs.

5. A hair-pin having at least one of two legs bent back inwardly betweensaid legs and forming a resilient abutment approxi- 10 mately parallelto and cooperating with the other leg.
